1.1 Background

This project is about providing a prototype of system alert for a people which is attach to this keychain for example car key.This project is combining Arduino and GSM technology. The function of GSM is to receive the information send from phone example call or SMS. Through this action, the Keychain will be ringing or buzz because the keychain is attach with the small buzzer and speaker act as indicator. It contact immediately to inform the location of the keychain in real time. The system covered one type of sensor as the basic of security system for home. The sensor is vibration sensor. The operation of this security system is illustrated in Figure 1.1. Figure 1.1 Communication Technologies INTRODUCTION CHAPTER 1 2 The new age of technology has redefined communication. Most people nowadays have access to mobile phones and thus the world indeed has become a global village. At any given moment, any particular individual can be contacted with the mobile phone. But the application of mobile phone cannot just be restricted to sending SMS or starting conversations. New innovations and ideas can be generated from it that can further enhance Technologies such as Infra-red, Bluetooth, which has developed in recent years goes to show the very fact that improvements are in fact possible and these improvements have eased our life and the way we live. Remote management of several home and office appliances is a subject of growing interest and in recent years we have seen many systems providing such controls. These days, apart from supporting voice calls a mobile phone can be used to send text messages Sending written text messages is very popular among mobile phone users. Instant messaging, as it is also known, allows quick transmission of short messages that allow an individual to share ideas, opinions and other relevant information. This project used the very concept to design a system that acts a platform to receive messages which in fact are commands sent to control different appliances and devices connected to the platform. This project designed a control system which is based on the GSM technology that effectively allows control from a remote area to the desired location. The application of our suggested system is immense in the ever changing technological world. It allows a greater degree of freedom to an individual whether it is controlling the household appliances or office equipmen t’s. The need to be physically present in order to control appliances of a certain location is eliminated with the use of our system. 3
